After a couple of very helpful replies to my query on this forum about polyester sheet supplies, Secol are sending me some 50 micron thickness sheets for placing between negative and Arches Platine paper when Ziatype printing.
Is the polyester sheet usable only once for this purpose, thinking that perhaps emulsion may adhere to the sheet and foul a second print, or can the same sheet be used several times?
Many thanks
